Final answer:
In the mid-nineteenth century, Southern states of the U.S. held a monopoly over the cotton industry and attempted to leverage this into political power to gain recognition from Great Britain for the Confederate States of America.
Step-by-step explanation:
During the mid-nineteenth century, there was a significant shift in the balance of political power in the United States, particularly within the Southern states. Who held the monopoly over political power in CTBC? This refers to the Southern states of the U.S., which had a near-monopoly over the cotton industry, a key economic asset at the time. These states supplied a vast majority of cotton to Great Britain and attempted to use this economic power to assert political influence, with the specific goal of convincing Great Britain to recognize the Confederacy during the American Civil War.
